Sliding sash windows are the classic window style. Originally installed in period properties throughout the Georgian and Victorian eras, they are now popular in both traditional and modern homes. Historically made from timber, today, their PVC-U  counterparts can match the wooden originals in terms of appearance while far surpassing them with regard to performance and maintenance.

If you’re a UK-based glazing installer and you want to offer your customers the best PVC-U sliding sash windows, you’ve come to the right place. In this blog, we’ll give you all the information to help you convince your customers why PVC-U sliding sash windows are the best option for their homes.

Sliding sash windows opening mechanism explained

Sash windows operate on either a weight and pulley system or a spring balance system. In the weight and pulley system, when you lift the window up or down, the weights move with the window allowing a smooth opening operation.

The spring balance opening system works in a similar way to the weight and pulley system. A PVC tube containing two springs is installed into the window frame. It creates a counterbalancing effect to allow each sash to slide smoothly open and close.

At Victorian Sliders®, our ECOSlide® Vertical Sliding Sash Windows feature spring balances in their design. Spring balances are more durable than weights and pulley systems and are the better choice for our PVC-U sash windows.

Innovative tilt-in functionality for easy cleaning access & optimum air circulation

Victorian Sliders ECOSlide® sash windows don’t just feature a smooth sliding opening and closing action like traditional timber sash windows. They also incorporate an innovative inward tilting feature into their design for easy access to the exterior of the window panes. This is particularly useful for upper storey windows and installations in multi-occupancy properties.

Both window sashes can be tilted inwards on a flexible hinge system. The windows can still slide up and down while tilted allowing for maximum flexibility and easy cleaning access to the exterior window pane and frame.

ECOSlide® sash windows also provide excellent ventilation through their air circulation capacity.
